Hello, Shinobi. I can tell you that they are definitely German. This video is from a German gay
company video from the 1990s called "GERO", which is a short form of a name beginning with the
Germanic element ger meaning "Spear". Now, I really don't know their names even the title of this
video, sorry, but at least you know where they are from. I hope its help, Shinobi.
